Pros of WebGL-Fluid-Simulation

• More interactive features, including mouse interaction and color customization
• Better performance optimization, allowing for smoother simulations on various devices
• Cleaner and more organized codebase, making it easier to understand and modify

Cons of WebGL-Fluid-Simulation

• Less physically accurate simulation compared to GPU-Fluid-Experiments
• Fewer advanced fluid dynamics features, focusing more on visual appeal than scientific accuracy
• Limited documentation and explanations of the underlying algorithms

Code Comparison

WebGL-Fluid-Simulation:

const splatStack = [];
const pointers = [];

class Pointer {
    constructor() {
        this.id = -1;
        this.x = 0;
        this.y = 0;
        this.dx = 0;
        this.dy = 0;
        this.down = false;
        this.moved = false;
        this.color = [30, 0, 300];
    }
}

GPU-Fluid-Experiments:

class Fluid {
    public var width(default, null):Int;
    public var height(default, null):Int;
    public var cellSize(default, null):Float;
    public var density(default, null):Float;

    var velocityRenderTarget:RenderTarget2Phase;
    var pressureRenderTarget:RenderTarget2Phase;
    var divergenceRenderTarget:RenderTarget;
}

The code comparison shows that WebGL-Fluid-Simulation uses JavaScript and focuses on user interaction, while GPU-Fluid-Experiments uses Haxe and emphasizes fluid dynamics properties.

Pros of fluid

• Implements multiple fluid simulation techniques (SPH, PIC/FLIP, APIC)
• Supports both 2D and 3D simulations
• Includes a GUI for parameter adjustment and visualization

Cons of fluid

• Less focus on GPU acceleration compared to GPU-Fluid-Experiments
• May have higher computational requirements for complex simulations
• Documentation could be more comprehensive

Code Comparison

fluid:

void FluidSolver::advect(float dt) {
    for (auto& particle : particles) {
        particle.position += particle.velocity * dt;
    }
}

GPU-Fluid-Experiments:

const advectionProgram = new GLProgram(advectionShader);
advectionProgram.bind();
gl.uniform2f(advectionProgram.uniforms.texelSize, 1.0 / simWidth, 1.0 / simHeight);
gl.uniform1i(advectionProgram.uniforms.uVelocity, velocity.read.attach(0));
gl.uniform1f(advectionProgram.uniforms.dt, dt);
gl.uniform1f(advectionProgram.uniforms.dissipation, config.VELOCITY_DISSIPATION);
blit(velocity.write);
velocity.swap();
